Alec Baldwin has reprised in his role as Donald Trump for the latest episode of Saturday Night Live’s Weekend Update, identifying the US president as the true martyr of the tragic Charlottesville rally.

A 12-year-old singing ventriloquist has been awarded US$1 (A$1.3) million prize and her own Las Vegas show after taking the America's Got Talent crown on the season 12 finale of the NBC reality competition.

He pointed out he was visiting a business with former federal Labor leader Kim Beazley, who sung Mr McGowan's praises, saying the 49-year-old was a family man who had empathy with ordinary West Australians.

"Mark is ready for the top job," Mr Beazley said.

"He is exactly what Western Australia needs at this point in time in our history. He's got safe hands."

Mr McGowan rejected Treasurer Mike Nahan's claim that Labor would have to immediately fire at least 2500 people from the public sector to achieve a $750 million savings target.

The opposition has promised to axe 20 per cent of the public sector's senior executive positions and trim down the number of government departments and agencies by the same amount.

Mr McGowan also refused to implement a new debt ceiling, which used to be $20 billion. It was breached by the Liberals and is now headed for $41 billion.

Labor's costings have it getting the state's budget back in surplus by $205 million by 2019/20, but debt would still rise to more than $39 billion.

"Debt would be lower than under the Liberal party's budget," he said.

"Clearly debt needs to be kept under control but it's a long-term plan.

"There's no magic solution. It will be up to WA Labor to turn that ship around but it will take time."
